[Bug 1765833] [NEW] bond intervals default to seconds; breaks existing configs

[Ryan Harper]

Public bug reported:

1. # lsb_release -r -d
Description:	Ubuntu Bionic Beaver (development branch)
Release:	18.04

2. # apt-cache policy netplan.io 
netplan.io:
  Installed: 0.34.1
  Candidate: 0.34.1
  Version table:
 *** 0.34.1 500
        500 http://archive.ubuntu.com/ubuntu bionic/main amd64 Packages
        100 /var/lib/dpkg/status

3. bonds with an mii-monitor-interval value of 100 should configure the
bond device with an mii-interval of 100 milliseconds.

% cat /sys/class/net/bond0/bonding/miimon
100

4.

cat /sys/class/net/bond0/bonding/miimon 
100000


This results in a 100+ second delay before a lacp bond device can transmit packets.
